At the character selection screen, highlight Mamma and press L1, Circle, R1, Down(2), R1, Circle, L1(2). If you entered the code correctly, a red balloon will appear over Sister Magpie. Move the cursor to her spot and Fwank will be playable.

Level skip

Pause the game and hold L1 + L2 for ten seconds, until the red cursor can not be moved by the D-pad. While those buttons are held, press Left, Triangle, X, Right, Circle, Triangle, Down.

Refill health

Pause the game and hold L1 + L2 for ten seconds, until the red cursor can not be moved by the D-pad. While those buttons are held, press Down, Right, Left, Triangle, Right, Down. Now when the game is paused, an option to restore your health will appear.

Refill ammunition

Pause the game and hold L1 + L2 for ten seconds, until the red cursor can not be moved by the D-pad. While those buttons are held, press Triangle, Left(3), Circle, Triangle, Down. Now when the game is paused, an option to refill your ammunition will appear.

Weapon power-up

Pause the game and hold L1 + L2 for ten seconds, until the red cursor can not be moved by the D-pad. While those buttons are held, press Left, Up, X, Circle. Now when the game is paused, an option to power-up the weapons will appear.

Play as a walking corpse

Enter the "Health refill" code to enable the "Health" option on the options menu. Then, pause the game immediately after dying, and before regenerating. Use the "Health" option to refill the life bar. Your character can now move around as a splattered corpse, totally invulnerable to enemies. However, since your own actions are limited, this trick is of limited value. However, it is an interesting thing to try on level 6 or during a two player game.
